The term green building or going green entails much more than just reducing energy consumption. The greening of a building includes improving the healthful nature of the building for improved human use. By improving the interior environment, human health and productivity are also improved. Many companies that have implemented green office upgrades report a reduction in lost time due to illness. The greening of schools may be one of our most important responsibilities.

In most regions, children spend about one-third of their lives in public school buildings. Many of those buildings are outdated and overcrowded. As these schools reach the end of their useful lives, the new school buildings that will replace them should be very green. The obvious changes must include higher energy efficiency, the use of alternate power sources, the maximization of natural heating and cooling methods and the overall protection of the environment.

Less obvious, and perhaps more important, is the interior environment of our schools. Most heating and cooling systems re-circulate the same air everyone is breathing and exhaling. Viruses are easily spread in this manner and sick building syndrome can result. New HVAC systems that exchange stale inside air for fresh outside air are becoming more economically feasible.

Most of the materials used to finish the interior of a school can be harmful. In a recent study, researchers found that products made from PVC emit gases that can cause developmental disorders in children. PVC is found in many plastic items from corner guards and wall rails to cafeteria seating and more.

Vinyl tile, carpet, wall coverings, paints, ceiling tiles, paneling, adhesives and more can emit VOC gases (Volatile Organic Compounds) that are released into the air, often for years after installation. VOC gases have been linked to cancer, blood disorders, learning disorders, birth defects and even death. All of these building products are now available in low-VOC and no-PVC content form.

One issue that stands between our children and green schools is funding. Public schools and most municipal or commercial buildings are constructed by the lowest bidder, often using the least expensive, yet durable materials. The initial cost of green building may discourage school planners from using this wonderful new technology. New thinking must prevail to change the way our school systems view the added building expenses.

Reducing energy use and particularly fossil fuel use is good for the environment and society, and saves money. Reducing or eliminating VOC gases and PVC emissions while cleaning the air circulated through our schools will strengthen the learning environment and improve the overall healthfulness of the children, faculty and staff. Ultimately, the cost is well worth the long-term benefits.
